Four checks before you buy
A short framework for buyers who are new to this material

Verify dry-fix details, anchor pull-out and seismic cases; shop drawings need manufacturer sign-off.
Finish & Color
Ceramic-coated wood/stone looks need sealed samples; control batch color variation.
Fire & Weather
Request fire, impact and absorption tests; coastal projects need salt spray and freeze-thaw data.
Japanese Brands
Nichiha, Kmew, Konoshima systems need matched trims; Toray material solutions can support spec development.
